These state-of-the-art models set new standards for coding, advanced reasoning, and AI agent capabilities, with Claude 4 Opus being recognized as the world's best coding model and Claude 4 Sonnet offering significant improvements over its predecessor.
Details
AvalAI continues to expand its model offerings with the addition of Anthropic's latest Claude 4 models. These models represent a significant advancement in AI capabilities, particularly for coding, complex reasoning, and agent workflows.
Anthropic
Claude 4 Opus: The most powerful model in the Claude family and currently the world's best coding model, with exceptional performance on SWE-bench (72.5%) and Terminal-bench (43.2%). It excels at sustained performance on long-running tasks requiring focused effort and thousands of steps. Documentation
Claude 4 Sonnet: A significant upgrade to Claude Sonnet 3.7, delivering superior coding capabilities (72.7% on SWE-bench) while responding more precisely to instructions. It offers an optimal balance between performance and efficiency. Documentation
Key Features
Hybrid Response Modes: Both models offer two modes - near-instant responses for quick interactions and extended thinking for deeper reasoning on complex problems.
Enhanced Tool Use: Both models can use tools during extended thinking, alternating between reasoning and tool use to improve responses.
Parallel Tool Execution: The ability to use multiple tools simultaneously for more efficient problem-solving.
Improved Instruction Following: More precise adherence to user instructions, reducing the likelihood of shortcuts or loopholes.
Enhanced Memory Capabilities: When given access to local files, these models demonstrate significantly improved memory capabilities, extracting and saving key facts to maintain continuity over time.
Pricing
- Claude 4 Opus: $15/$75 per million tokens (input/output)
- Claude 4 Sonnet: $3/$15 per million tokens (input/output)

"content": "Create a recursive function in Python to calculate the Fibonacci sequence.",
}
],
)
print(completion.choices[0].message.content)import { OpenAI } from "openai";
const client = new OpenAI({
